NIBE PVT 40 makes it possible for your heat pump to use NIBE PVT panels as a heat source. The heat pump regulates the temperature of incoming brine in the summer, and closes the shunt valve in the winter when the temperature reaches the set value. The NIBE PV-T collector is an alternative, innovative, heat source for use with NIBE ground source heat pumps, removing the requirement of a ground or bore hole collector array . The PV-T collectors produce electrical energy that can be used to operate a ground source heat pump.
NIBE PV is an integrated solution which is based on a fully modular system with several basic sizes: 4 / 8 / 12 / 16 / 20 kW. Each basic package has nominal power of 4 kW and consists of 10 panels, mounting parts and an inverter with communication module, all of which are ready for installation. The solar package can easily be expanded with additional solar panels for optimum use of roof space. NIBE PV comprises of monocrystalline silicon cell panels which use PERC technology, with an output of 400 Wp. The solar panels are elegant, all-black panels. NIBE PV harnesses sunlight all year round and converts it into electricity. NIBE PV can be connected to your NIBE heat pump* for maximum energy efficiency. Thanks to smart technology, the product gives you control over your energy consumption and will be a key part of your connected home. The efficient control system automatically adjusts the indoor climate for maximum comfort, and you do nature a favour at the same time. * applies to systems which can be connected to NIBE Uplink and myUplink.

Accessory card. AXC 40 is used to enable connection and control of Mixing valve controlled additional heat, Pump for hot water circulation, Groundwater pump
The NIBE FLM is an exhaust air module with built-in fan, specially designed for combining recycling of mechanical exhaust air with a NIBE ground source heat pump, providing an integrated solution for ventilation, hot water and heating. The NIBE FLM has a high fan capacity and low noise level. Energy is recovered from the ventilation air; even when the heat pump is not in operation, energy is stored in the ground or soil collector and exhaust air energy is thus put to maximum use. Thanks to smart technology, the product gives you control over your energy consumption and will be a key part of your connected lifestyle. The efficient control system automatically adjusts the indoor climate for maximum comfort, and you do nature a favour at the same time.
